have itunes add movies automatically

Is it possible to have itunes add movies automatically from a NAS drive?
I was imagining I could run iTunes, streaming to the aTV, on an old fanless G4 cube, but with no monitor hooked up. Instead I'd like to just use another computer to put content on a NAS, from which the cube could pick it up.

Yes I just discovered that, first hit on Google, typically..
I noticed it's directly moved into a another folder bearing the file's name, is this possible to change? I like to have my movie files sorted by country.
Can I use the same iTunes library for my main computer?
Does the NAS need to support "iTunes server", or is that something else?
thanks!

It seems to make no difference, and I only had "organize" ticked in first place. Come to think of it, with a NAS I must use the web browser or FTP program? Would it be simpler (and possible) to have an Airport Extreme with a hard drive connected, and can both computers access the same iTunes library from it from Finder?
